He hardware it is the structure that gives physical support on the computer while the software is the operational support. Together, hardware and software are essential elements for the operation of the computer and other electronic devices.
For example, the screen where we read the information and the mouse we use to navigate this page are hardware. The Internet browser or browser to visit this page and the operating system on which it runs browser they are software.

What is hardware?
He hardware it consists of the physical components of the computer or computer, that is, everything that can be touched.
The word “hardware“means” hard merchandise “or” hard drive “as a direct reference to the physical structure of a computer.
He hardware makes the computer work. The central processing unit (CPU) processes the information that can be stored on the memory devices. The sound card provides sound to the horns, and the video card provides image to the monitor.
Basic parts of the hardware
He hardware it has four main parts: input, memory, processor and output.
Entry o input: this is the part of hardware with which the data is entered. For example, the keyboard, scanner, barcode reader.
Memory: stores information, programs, and data. Also known as RAM (for its acronym in English) random access memory).
Processor: is the electronic brain of the computer. The processor analyzes, examines, alters, and executes the instructions of the software of the computer.
Output o output: are the devices that show the results. For example, on the monitor we can see images, through the horns the sound comes out and through the printer a certain text is put on paper.
Components of the hardware
He hardware has several components.
The big card o motherboard controls and connects the other components of the hardware. There are slots or slots where connections are made to video and sound cards, memory chips, and the CPU.
CPU central processing unit
The central processing unit, also known as the microprocessor, is the center where information and data are analyzed, calculated, and dispatched. The best known models are Pentium, Celeron, Athlon and Sempron.
There are two types of memory:
- RAM: random access memory. The more RAM a computer has, the more programs can be used simultaneously.
- ROM memory: Read memory that comes on the motherboard and cannot be altered.
Input and output devices
They are the devices needed to enter and obtain information. This category includes the monitor, mouse, horns, keyboard and game controls.
It is all these components where the information can be stored. For example, hard disk, CD-ROM, DVD, USB memory, among others.
What is software?
Software is the code that sets the set of instructions that your computer follows. Includes untouchable programs and operating systems.
The word “software“comes from English meaning” soft goods “and has become globalized as synonymous with computer instructions.
A computer can run without software installed. However, without an operating system, an error will probably be generated or no information will appear.
Kind of software
Several types of software depending on the function.
The basic input / output system or BIOS (for the acronym in English) basic input output system) is the software computer dynamics.
The operating system controls the physical part after power up. Examples of operating systems are Microsoft Windows, Mac OS X and Linux for personal computers, iOS and Android for tablets and smartphones.
An application is a software designed to perform a specific task. For example, the Photoshop is an image processing application, Google Chrome is an application for surfing the Internet.
Installing programs or applications on your computer increases the functionality available. For example, a word processor is not required for your computer to work, but it allows you to create documents.
Software of communication
These software they control the communication processes between computers. Examples: email, Skype.
It is the operating code of an electronic computer. Examples: software TV, Microwave, Video Games.
